Impact resistant wrapping system

ABSTRACT

An impact resistant wrapping system of the invention has a sheetlike wrapping body (1) formed of gas-barrier flexible wall members (11) and (12) between which wall chambers (14) closely partitioned or partially joined to one another are formed. The sheetlike wrapping body (1) is provided with an intake tap (3) capable of injecting gas into the wall chambers and exhaust taps (5) for releasing the gas from the wall chambers (14), which intake and exhaust taps are integrated so as to be used in common or formed separately. The exhaust taps (5) are arranged between the closely partitioned wall chambers (14) in one line or two or more lines intersecting to the wall chambers (14) so that the adjacent wall chambers (14) communicate with one another through the exhaust taps (5), thereby allowing the exhaust tap (5) of the outermost wall chamber (14) to communicate to the outside of the sheetlike wrapping body (1).

TECHNICAL FIELD

This invention relates to an impact resistant wrapping system. Moreparticularly, this invention relates to an improvement in versatilityand repetitious usability of such an impact resistant wrapping systemcapable of forming an impact resistant chamber inflatable with gasaround an article to be protected.

BACKGROUND ART

There have been so far known wrapping implements having an impactresistant chamber inflatable with gas as described in, for example,Japanese Utility Model Application Public Disclosure No. HEI 4-3974(A).

This conventional impact resistant wrapping system comprises gas-barrierflexible wall members between which partitioned wall chambers areformed, and a check valve for introducing air into the wall chambers.The wrapping system is affixed to the inner surface of a packing case inuse. Before or after putting the article to be protected into thepacking case, the air is injected into the wall chambers through thecheck valve so as to form a shock-absorbing space with which a gapbetween the packing case and the article is filled in.

The aforementioned prior art impact resistant wrapping system hassuffered disadvantages such that it invariably calls for a packing casebecause it must be integrally united to the packing case in use, andcannot protect an article which is notably different in shape from thepacking case and thus is not versatile. Furthermore, since theconventional wrapping system is bonded to the packing case and is notfurnished with an effective means for releasing the air from the wallchambers, it is difficult to reuse.

This invention was made in view of the foregoing problems and has theobject of providing an impact resistant wrapping system having highversatility and repetitious usability and capable of repeatedly wrappingarticles of various shapes and sizes.

SUMMARY OF THE INVENTION

To solve the problems as described above, according to the presentinvention, there is provided an impact resistant wrapping systempossessing the following:

That is, the impact resistant wrapping system according to thisinvention comprises a sheetlike wrapping body formed of gas-barrierflexible wall members which are closely partitioned or partially joinedto one another. The sheetlike wrapping body is provided with an intaketap capable of injecting gas into the wall chambers and exhaust taps forreleasing the gas from the wall chambers. The intake and exhaust tapsare integrated so as to be used in common or formed separately. Theexhaust taps are arranged between the closely partitioned wall chambersin one line or two or more lines intersecting to the wall chambers sothat the adjacent wall chambers communicate with one another through theexhaust taps, thereby allowing the exhaust tap of the outermost wallchamber to communicate to the outside of the sheetlike wrapping body.Also, the exhaust tap in the aforesaid wrapping system may be formed ofa flat cylinder made of thin synthetic resin film.

Furthermore, an exhaust pipe, which is provided in its peripheralsurface with a number of pores and can be inserted successively into theexhaust taps, may be used.

Moreover, the impact resistant wrapping system according to thisinvention comprises a sheetlike wrapping body formed of gas-barrierflexible wall members between which partitioned wall chambers are formedso as to partially communicate with a plurality of passages. Thesheetlike wrapping body is provided with an intake tap capable ofinjecting gas into the wall chambers and exhaust taps for releasing thegas out of the wall chambers. The intake and exhaust taps are integratedso as to be used in common or formed separately. The wrapping body isprovided with intermediary taps disposed between the closely partitionedwall chambers, thereby allowing the exhaust tap of the outermost wallchamber to communicate to the outside of the sheetlike wrapping bodythrough the plurality of passages.

According to the aforementioned structure, the wall chamber in thesheetlike wrapping body is inflated with gas injected through the intaketap to form a shock-absorbing space. Since the wall chamber in thesheetlike wrapping body is subdivided into smaller chambers, thewrapping body can be folded or bent so as to protect the articles ofvarious shapes or sizes. The gas injected in the wall chambers caneasily be released continuously by inserting the exhaust pipe throughthe exhaust taps arranged in line. Since the sheetlike wrapping body isdeflated into a flat shape by releasing the gas out of the wallchambers, it can be used repeatedly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the impact resistant wrapping system according to thisinvention will be described hereinafter with reference to theaccompanying drawings. FIG. 1 through FIG. 8 illustrate a firstembodiment of the impact resistant wrapping system according to thisinvention.

As shown in FIG. 1, a sheetlike wrapping body 1 in this embodiment isformed by putting two rectangular flexible wall members 11 and 12 one ontop of the other and sealing, with an adhesive or by thermal welding,the four peripheral sides and portions which are parallel to two of theaforesaid four sides and spaced at regular intervals to thereby formseal portions 13. Thus, there are definitely partitioned rectangularwall chambers 14 among the seal portions 13 between the flexible wallmembers 11 and 12. The flexible wall members 11 and 12 have gas-barrierproperties such as impermeability to gases or extremely low gaspermeability as well as moderate flexibility to enable the wrapping bodyto be elastically deformed, conforming to the shape of an article 20 tobe wrapped. The flexible wall member may be formed of a monolayeredsynthetic resin film, multilayered synthetic resin film or materiallaminated with a metal film. The flexible wall members 11 and 12preferably have magnetic-resistant and antistatic properties.Incidentally, in case that the monolayered or multilayered syntheticresin film is used as the flexible wall members 11 and 12, it ispreferable to use a film of 0.02 to 0.50 mm in thickness.

Onto the opposite short sides of the sheetlike wrapping body 1, aconnecting means 2 composed of band-shaped male and female velvetfasteners are affixed.

At one of the short sides of the seal portions 13 defining each wallchamber 14 in the sheetlike wrapping body 1, an intake tap 3 isdisposed. As illustrated in FIG. 2 and FIG. 3, the intake tap 3 isnormally in its closed state, but opens by inserting thereinto aninjection pipe 4 or any other means, so that gases 10 such as air can beinjected into the wall chamber 14 of the sheetlike wrapping body 1.Thus, the intake tap is formed of a cylinder of flat synthetic resinfilm having a thickness of about 0.01 to 0.06 mm and is connected withan intake port 15 pierced through a part of the aforesaid seal portion13.

At one of the long sides of the seal portions 13 defining each wallchamber 14, an exhaust tap 5 is disposed. The exhaust tap 5 is made ofthe same material and has the same structure as those of the aforesaidintake tap 3. The exhaust tap is normally in its closed state, but isbrought into an open state by inserting thereinto an exhaust pipe 6which is provided in the peripheral surface with a number of pores 6'opening in various directions so as to release the gas filled in thewall chamber 14, as shown in FIG. 8. The exhaust taps 5 are arranged onthe line 30 intersecting perpendicularly to each wall chamber 14.Furthermore, the wall chambers 14 are respectively connected with theadjacent wall chambers through the exhaust taps 5 and exhaust ports 16'pierced partially through the aforesaid seal portions 13. One of theoutermost wall chambers 14 communicates with the outside of thesheetlike wrapping body 1 through an outlet port 16 pierced through apart of the outermost seal portion 13 having the exhaust tap 5. Theaforesaid exhaust pipe 6 is successively inserted through the exhausttaps 5, outlet port 16 and exhaust ports 16'.

Since the whole constituent components including the intake taps 3 andexhaust taps 5 are made by simply bonding lamellar sheetlike material,the wrapping system can be easily manufactured at a low cost. Besides,since the wrapping system including the intake taps 3 and exhaust taps 5can be made flat like a thin sheet, it is advantageous in tucking awayand storing.

When the wrapping system is used, the induction pipe 4 shown in FIG. 2is inserted into the wall chambers 14 in the state shown in FIG. 1through the intake port 15 and intake taps 3, so that the wall chambers14 in the sheetlike wrapping body 1 can be inflated with a breath or byinjecting gas 10 by use of an air compressor or the like, as shown inFIG. 5. Then, the article 20 to be protected is wrapped with theinflated wrapping body 1 and retained by joining together the connectingmeans 2. As a countermeasure, after wrapping the article 20 with thewrapping body of FIG. 1 and joining the connecting means 2, the gas 10may be injected into the wall chambers 14 in the sheetlike wrappingbody 1. It is possible to inject the gas into the wall chambers by usinga compressor 8 as shown in FIG. 4 in place of the aforesaid inductionpipe 4. The compressor has a simple valve 81 made of synthetic resin anda blast nozzle 82 and serves to discharge the air by being squeezed.When pulling out the induction pipe 4 after injecting the gas 10 intothe wall chambers 14, the intake tap 3 assumes its flat state by theaction of the pressure of the gas filled in the wall chamber, as shownin FIG. 3, thus inextricably confining the gas 10 within the wallchamber 14. The exhaust tap 5 has the same function of confining the gas10 as the intake tap.

Although FIG. 6 shows the case where a columnar article 20 to beprotected is wrapped, it is possible to wrap an article of any shapeother than such a columnar shape, because the wall chambers 14, eachformed in a long strip, are arranged side by side so as to be freelyfolded or bent even in the deflated or inflated state. Moreover, some ofthe wall chambers 14 may be selectively inflated in use as shown in FIG.7.

The article 20 surrounded by the inflated sheetlike wrapping body 1 canbe fully protected by the gas 10 filled in the wall chambers 14 in thesheetlike wrapping body 1, because the gas in the inflated wall chambersserves to absorb shocks. Particularly, since the wall chambers 14 areclosely partitioned, even when one of the wall chambers 14 is broken topermit the gas in the wall chamber to escape, the shock-absorbingfunction of the other wall chambers 14 of the wrapping system is notaffected by the leakage of gas.

When the article 20 needs to be unpacked, the connecting means 2 areunfastened to free the article 20. Then, the exhaust pipe 6 is insertedinto the wall chambers 14 through the outlet port 16 as shown in FIG. 8,so as to permit the gas 10 in the wall chambers 14 to spontaneouslyescape out of the sheetlike wrapping body 1 by its own pressure. Aroundthe end of releasing the gas 10, external pressure may be exerted toeach wall chamber 14 to increase the inner pressure in the wrappingbody. Since the exhaust pipe 6 has many pores 6' opening in alldirections, the gas 10 can be smoothly released without controlling thestate of inserting the exhaust pipe 6 into the wall chambers.

When the gas 10 is released from the wall chambers 14 of the sheetlikewrapping body 1, the sheetlike wrapping body assumes its flat state, sothat it can be arbitrarily reused.

FIG. 9 shows a second embodiment of the impact resistant wrapping systemaccording to this invention. In this embodiment, the intake taps 3 inthe aforementioned first embodiment are arranged in a similar manner tothe exhaust tap 5 on the line 30, but in the opposite direction. Eachintake tap 3 is provided with an intake port 15' pierced partially theseal portion 13.

According to this embodiment, the exhaust pipe 6 can be continuouslyinserted into the intake taps 3, so that the gas 10 can besimultaneously introduced into the wall chambers 14. Furthermore, sincethe intake taps 3 and the exhaust taps 5 are arranged in the samemanner, the system of this embodiment can be readily produced.

FIG. 10 and FIG. 11 show a third embodiment of the impact resistantwrapping system according to this invention. In this embodiment, thewall chambers 14 extending in the longitudinal direction of thesheetlike wrapping body 1 are divided by the seal portion 13'perpendicular to the longitudinal direction. The divided wall chambers14 are connected via intermediary taps 9 similar to the intake tap 3 andexhaust tap 5.

This embodiment can be suitably used for wrapping a flat article 20 insuch a manner that the wrapping body is doubled along the divided line(seal portion 13') so as to hold the article therebetween.

FIG. 12 shows the fourth embodiment of the impact resistant wrappingsystem according to this invention, wherein an intake passage 17 havingone intake port 15 confronts the intake taps 3 disposed in the wallchambers in the sheetlike wrapping body 1.

According to this embodiment, gas 10 can be introduced into the wallchambers 14 through the intake port 15 and the intake taps 3 at onetime, but need not be introduced individually into the wall chamber inthe sheetlike wrapping body 1.

FIG. 13 and FIG. 14 show a fifth embodiment of the impact resistantwrapping system according to this invention. In this embodiment, thesheetlike wrapping body 1 as used in the foregoing second embodiment isformed in a T-shape foldable into a hexahedron so as to be placed withina container box 40. This wrapping body has also the intake passage 17 asseen in the aforementioned fourth embodiment.

This embodiment can be used in the conventional manner as illustrated inFIG. 14.

FIG. 15 and FIG. 16 show a sixth embodiment of the impact resistantwrapping system according to this invention. In this embodiment, insteadof the intake port 15 as described above, a protruding piece 18 having agas capsule 7 contained in the intake passage 17 is formed.

The gas capsule 7 has a partition membrane 72 for partitioning theinside of a shell 71 into two parts for separately containing a liquidor solid substance 73 and another substance 74. By pressing the gascapsule to break the partition membrane 72, both the substances 73 and74 are mixed with each other to react chemically and generate gas. Forexample, in order to generate oxygen as the gas, there may be usedmanganese oxide as the substance 73 and a hydrogen peroxide solution asthe substance 74. As a countermeasure, it is desirable to use, as thesubstance 73, various solid substances obtained by bonding solublederivatives with gas, which have been recently used for a chemicalexperiment, horticulture gardening and aquarium. In this case, water maybe used as the other substance 74. However, it is preferable to use thesubstances 73 and 74 capable of chemically interacting withoutgenerating a high temperature and damaging the shell 71. Furthermore,the shell 71 may be made of a synthetic resin material havinglabyrinthian fine pores which allow the gases to pass therethrough, butprevent liquid components from leaking out of the shell 71.

According to this embodiment, when the wrapping system is first used,the wall chambers 14 in the sheetlike wrapping body 1 can be inflatedwith the gas 10 generated from the gas capsule 7 without need to supplythe gas 10 into the wall chambers in the same manner as the foregoingembodiments. When reusing the wrapping system two or more times, theprotruding piece 18 is cut to form the intake port 15 so as to introducethe gas into the wall chambers in the same manner as the foregoingembodiments. In and after the second use, the part accommodating the gascapsule 7, which becomes unserviceable, may be folded back upon thesheetlike wrapping body 1 having the wall chambers 14.

FIG. 17 shows a seventh embodiment of the impact resistant wrappingsystem according to this invention. In this embodiment, the compressor 8shown in FIG. 4 having the function of the intake port 15 is integratedinto the wrapping body in place of the gas capsule 7 seen in theforegoing sixth embodiment.

This embodiment makes it possible to repeatedly inject the gas 10 intothe wall chambers by use of the compressor 8 and simplify the structurein comparison with the aforementioned sixth embodiment.

FIG. 18 and FIG. 19 show an eighth embodiment of the impact resistantwrapping system according to this invention. In this embodiment, anintake tap 3 having a narrow inlet 31, which leads to the intake port 15and a spreading round outlet 32 is formed in common with the pluralityof wall chambers 14 so as to disperse the gas 10 toward the wallchambers 14 from the intake port 15 through spreading portions 15". Theadherent connecting means 2 are each formed of a pressure-sensitiveadhesive 2' covered with a releasing sheet.

According to this embodiment, the article 20 to be protected can bewrapped within the wrapping body folded like an envelope. Besides, thewrapping system in its folded state can be made thin due to a decreasednumber of the intake tap 3 and the thin connecting means 2 having such asimple structure as described.

FIG. 20 and FIG. 21 show a ninth embodiment of the impact resistantwrapping system according to this invention. In this embodiment, theseal portion 13 for dividing the inner space of the sheetlike wrappingbody 1 into two wall chambers 14 is arranged in a continuous zigzag.Each wall chamber 14 elongated in zigzag is subdivided into generallyU-shaped compartments by intermediary taps 9. Correspondingly, theintake tap 3 and exhaust tap 5 are provided with seals 33 and 5' capableof opening and closing and shaped generally in a fork. The protrusionlength L and width W of each of the intake tap 3 and exhaust tap 5 areon the order of several millimeters to some tens of millimeters.

According to this embodiment, the gas 10 filled in the wrapping body canbe discharged by pressing the inflated wall chambers 14 without usingthe exhaust pipe 6 as described above. The intermediary taps 9 in thisembodiment have the function of the exhaust tap 5. Furthermore, sincethe width W of the intake port 15 is large, the gas 10 can be easilyinjected.

FIG. 22 shows a tenth embodiment of the impact resistant wrapping systemaccording to this invention. This embodiment includes a lattice-shapedseal portion 13 to subdivide the wall chambers 14 as found in the firstembodiment. The subdivided wall chambers 14 are partially connected tolaterally adjacent wall chambers 14, so that only one intake tap 3 issufficient for injecting the gas.

According to this invention, since the surface of the wrapping bodyformed by the inflated wall chambers 14, it comes in contact with thearticle 20 to be protected in a small wave form, thus increasing thefunction of absorbing shocks. By using intermediary taps 9 for partiallyconnecting the adjacent wall chambers 14 to one another, even if a partof the wall chambers is broken, the gas 10 can be prevented from leakingfrom other wall chambers.

FIG. 23 and FIG. 24 show an eleventh embodiment of the impact resistantwrapping system according to this invention. One of the flexible wallmembers 11 and 12 in this embodiment is made of relatively thin materialforming wavy-shaped or semicylindrical ridges, and the other wall memberis made relatively thick. Thus, wall chambers 14 are each made slender,but generally interconnected with one another.

The wrapping system of this embodiment may be provided with at least oneset of intake tap 3 and exhaust tap 5. By using one series of the wallmembers 11 and 12, which are each formed in a wavy or semicylindricalshape, as an inside surface coming into face contact with the article tobe wrapped, the outside surface of the wrapping system can be made flat.

FIG. 25 and FIG. 26 show a twelfth embodiment of the impact resistantwrapping system according to this invention. This embodiment is the sameas the aforesaid eleventh embodiment except for the connecting means 2in the eleventh embodiment. This wrapping system can be placed inside anenvelope 100.

According to this embodiment, the wrapping system can be suitably usedas an inner package.

FIG. 27 shows a thirteenth embodiment of the impact resistant wrappingsystem according to this invention. This embodiment has the flexiblewall members 11 or wall members 12, which are each formed in asemicylindrical shape to assume a wavy surface as a whole, and smallwavy members each disposed between the adjacent wavy wall members, so asto have a double wavy structure. In this embodiment, the surface definedby the wall members on the other side than that on which the wavy wallmembers are formed is made flat. The wall chambers 14 thus formed iseach made slender, but generally interconnected with one another.

According to this embodiment, the interior surface formed by the doublewavy structure is made smooth and flat.

FIG. 28 shows a fourteenth embodiment of the impact resistant wrappingsystem according to this invention. The wrapping body 1 of thisembodiment is provided in its central portion with a relatively largecutout 40.

According to this embodiment, since an article 20 to be wrapped is heldby fitting the whole or one part such as a corner of the article intothe cutout 40, the article 20 can be protected from shock and steadilywrapped without using a specific retaining means such as the element 2in the foregoing embodiments.

FIG. 29 shows a fifteenth embodiment of the impact resistant wrappingsystem according to this invention. The wrapping body 1 of thisembodiment is provided in its central portion with relatively smallcutouts 40.

According to this invention, when packing an article 20 to be wrappedwithin an enclosure formed by the sheetlike wrapping body 1, the cutout40 is used as a non-contact means so that the article 20 fitted into thecutout 40 can be prevented from coming into touch with the wrapping body1, or it serves as a peephole for observing the article contained in thewrapping system.

FIG. 30 and FIG. 31 show a sixteenth embodiment of the impact resistantwrapping system according to this invention. The sheetlike wrapping body1 in this embodiment is integrated with a bag 50. That is, one of theflexible wall members, 12, of the sheetlike wrapping body 1 is common tothe bag 50. The bag 50 has a lid 60 with an adhesive 70 for sealing theopening of the bag.

According to this embodiment, an article 20 to be protected can bewrapped only by being put into the bag 50 and closing the bag with thelid 60. Otherwise, the bag 50 may be stuffed with cushioning material,so that the resistant wrapping system of the invention can be used as afiller or packing material, but not as a means for wrapping the article20.

FIG. 32 shows a seventeenth embodiment of the impact resistant wrappingsystem according to this invention. In this embodiment, the sheetlikewrapping body 1 is laminated with a sheet 80 having a lid 60 and sealedalong its fringe portion so as to form an envelope.

This embodiment has the same function and effect as the aforementionedsixteenth embodiment.

FIG. 33 shows an eighteenth embodiment of the impact resistant wrappingsystem according to this invention. In this embodiment, the sheetlikewrapping body 1 is attached to a foam cushion sheet 90.

The impact resistant wrapping system of this embodiment is suitably usedas a cushion means, but not as a means for wrapping the article 20.

FIG. 34 shows a nineteenth embodiment of the impact resistant wrappingsystem according to this invention. The sheetlike wrapping body 1 ofthis embodiment is formed by letting the wrapping body 1 of theaforenoted eighteenth embodiment have cutouts 40.

According to this embodiment, an article 20 wrapped by the wrappingsystem is prevented from coming in touch with the sheetlike wrappingbody 1 by means of the cutouts 40. In this embodiment, other cushionmeans may be fitted into vacant cutouts 40 in wrapping the article.

FIG. 35 shows a twentieth embodiment of the impact resistant wrappingsystem according to this invention, wherein a cutout 40 extends from anintake port 15 to ribs 15A of the sheetlike wrapping body 1.

According to this embodiment, an article 20 wrapped by the wrappingsystem is prevented from coming in touch with the sheetlike wrappingbody 1 by means of the cutout 40. In this embodiment, other cushionmeans may be fitted into the cutout 40 along with the article.

FIG. 36 and FIG. 37 show a twenty-first embodiment of the impactresistant wrapping system according to this invention. The wrappingsystem of this embodiment is formed by folding the sheetlike wrappingbody 1 into two, and joining both ends of the folded wrapping body toeach other, so as to assume a bag shape. To one end of the sheetlikewrapping body 1, there is joined a lid member 50. The lid member 50 isformed like a bag and has an open slit 60. Repeatedly usable connectingmeans 2 formed of adhesive are attached one onto either surface(opposite sides of the folded wrapping body 1) of the lid member 50.

According to this embodiment, an article 20 to be protected can becontained in the bag-shaped sheetlike wrapping body 1. If the article 20is thin, it may be admitted into the bag-shaped lid member 50 throughthe open slit 60. The lid member 50 folded back onto the sheetlikewrapping body 1 and fastened by the connecting means 2 serves toreinforce the wrapping body 1. Likewise, the lid member 50 thus foldedback and fastened onto the wrapping body 1 for accommodating the thinarticle 20 increases the cushioning effect brought about by the wallchambers 14.

According to the purpose for which the article to be protected istransported or carried, a message card, a list for goods to betransported or the like may be inserted into the open slit 60.Furthermore, since the lid member 50 can be folded onto either side ofthe sheetlike wrapping body, different address cards may be attached oneonto either side of the lid member 50, so that the wrapping system canbe used as a communication means to be sent between two places.

As the other measure than the aforesaid embodiment, the intake tap 3 maybe omitted by using the exhaust pipe 6 to be inserted through theexhaust tap 5 for introducing the gas 10 into the wall chambers 14 inthe sheetlike wrapping body 1.

Moreover, the intake tap and exhaust tap 5 may be changed to those usedin the other embodiments as specified above.

Besides, according to the usage, the wrapping system of the inventioncan be used as cushioning means for a floor cushion, mattress and so on.

INDUSTRIAL APPLICABILITY

As is apparent from the foregoing, since the impact resistant wrappingsystem according to the present invention has the partitioned wallchambers inflatable with gas, it can be folded or bent into any shapeand any size in conformity with the shape and size of an article to beprotected. Since the gas filled in the wall chambers can be continuouslyreleased through the exhaust taps arranged in line, the wrapping bodyinflated with gas can easily be deflated, thus resuming its originalsheetlike shape, so that versatility and repetitious usability of thewrapping system can be heightened.

Since the wrapping system of the invention has a simple structureincluding the intake tap and exhaust taps, it can easily be manufacturedat a low cost. Furthermore, since the wrapping system including theintake tap and exhaust taps is made thin and flat, it is advantageous intucking away and storing.

In addition, the gas filled in the wrapping system can be swiftlyinjected into and released from the wall chambers with a simpleoperation. Moreover, since the gas intake and exhaust can be carried outthrough a plurality of intake and exhaust passages, quick inflation anddeflation of the wrapping body can be accomplished.

Besides, since an article to be protected can be admitted into abag-like wrapping body, the article can easily be wrapped. The wrappingsystem of the invention further has an effect of increasing thecushioning effect by incorporating another cushioning material in thebag-like wrapping body.
